------------------- * Add a weighted fitting routine for the zhao burge transforms based on fiducial variance seen in dither analysis.
1.13.0
------------------- * Add WCS object validation check (passing an empty WCS in SolvePointing causes problems). * Add FVC center pixel info for LCO. * Switch to using Pramod's new Gaia DR2 table when running at Utah. * Re-implement nudge correction with flexure handling and separate model for outer FIFs.
1.12.0
------------------ * Add new parameters for offset function. Includes new parameters and expanding use of Moffar profile past core.
1.11.2
------------------ * limit gaia source queries to 250 brightest stars per gfa (speeds up crowded field guiding)
1.11.1
------------------ * remove print statements
1.11.0
------------------ * Add new guide fitter (SolvePointing class), implements a gaia based iterative fitter for pointing solutions. * Add sped up array based conversions between wok and positioner coords.
